+- A long-standing bug (:ghc-ticket:`16893`) which can cause some applications
+  of ``unsafeCoerce`` to segmentation fault is only partially fixed in this
+  release. This release only avoids this issue in the uses of ``unsafeCoerce``
+  in ``Data.Typeable.Internal``, which was the proximate cause of
+  :ghc-ticket:`16893`.
+
+  However, it is possible that this bug could manifest in user-code using
+  ``unsafeCoerce`` to perform dynamic type checks. See the :ghc-ticket:`ticket
+  <16893>` for details.
 
+  We expect that this issue will be fixed in the next major release of GHC.
